GAS-BURNER ATTACHMENT.

Specification of Letters Patent.

Patented Dec. 13, 1910.

Application filed March 14, 1910. Serial No. 549,158.

To all whom it may concern:

Be it known that 1, MARK G. RAY, citizen of the United States, residingat Richmond, in the county of Henrico and State of Virginia, haveinvented certain new and useful Improvements in Gas-Burner Attachments,of which the following is a specification.

This invention relates to gas burner attachments and has for its objectthe provision of a comparatively simple and thoroughly e'tlicient deviceof this character, capable of being readily attached to a candlestick orother support, thereby to form a drop light.

A further object is to provide a gas fitting including a casing having athreaded terminal for engagement with a burner and provided with anangularly disposed nipple for connection with a gas tube or conductor.

A further object is to provide the casing with a tapered plug adapted tofrictionally engage the walls of a candle-stick or other suitablesupport, thereby to prevent accidental displacement of said casing.

A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability andefficiency, as well as to reduce the cost of manufacture.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

For a full understanding of the invention and the merits thereof,reference is to be had to the following description and accompanyingdrawings, in which:

Figure 1 is a. side elevation of a gas burner constructed in accordancewith my invention, showing the same in position on a candle-stick; Fig.2 is a vertical sectional view of the fitting detached; Fig. 3 is aperspective View; Fig. 1 is a vertical sectional View illustrating amodified form of the invention.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The improved gas fitting forming the subject matter of the presentinvention coniprises a casing 5 having a reduced extension 6, theexterior walls of which are threaded for detachable engagement with agas burner 8, there being a circumferential shoulder 9 formed on thecasing at the base of the extension 6 and adapted to bearagainst thelower end of the burner 8, as shown.

Secured to or formed integral with the casing 5 is an angularly disposednipple 10 for connection with a tube or conductor 11 leading to asuitable source of gas supply, said casing being provided withintersecting passages 12 and 13 through which the gas flows from theconductor 11 to the burner tip 14..

The base of the casing 5 is provided with a flat bearing surface 15which forms an abutment for a tapered plug 16, there being a threadedsocket 17 formed in the base 15 and preferably disposed in verticalalinement with the extension (3, as shown. The plug 16 may be formed ofrubber, cork, asbestos or other yieldable material and is provided witha vertically disposed bore 18 adapted to receive a bolt or similarfastening device 19, which latter engages the threaded socket 17 andserves to clamp the plug in position on the base 15. The lower or smallend of the plug is preferably countersunk at 20 to receive the head ofthe screw or fastening device 19. The plug 16 is adapted to be insertedin the mouth of a candle-stick or other suitable support, indicated at21, the tapered walls of the plug, by frictional engagement with theinterior walls of the candle-stick, serving to retain the fitting inposition thereon and thus permit the candle-stick to be used as anordinary drop light. If desired however, the plug 16 may be inserted inthe mouth of a bottle, jar or the like, or in the bowl of an oil lamp,without departing from the spirit of the'invention.

It will here be noted that by making the plug 16 of yicldable material,said plug may be lnserted in the threaded burner receiving opening of alamp or the like without injury to the threads.

In Fig. 4 of the drawings, there is illustrated a modified form of theinvention in which the base of the casing is provided with a dependingstem 22 having its lower end threaded for engagement with a clamping nut23, said casing being provided with spaced laterally extending flanges24 and 25 for engagement with the tapered plug and burner, respectively.

The device is extremely simple in construction and may be manufacturedand placed on the market at a coinpartively small cost.

Having thus described the invention, What is claimed as new is:

l. A device of the class described includ ing a casing having angularlydisposed passages for connection with a burner and gas tube,respectively, and a tapered plug formed of yieldable material dependingfrom the casing for frictional engagement with the walls of a supportingsocket.

2. A device of the class described including a casing having 'angularlydisposed passages for connection with a burner and gas tube,respectively, a plug formed of yieldable material engaging the base ofthe easing and adapted to frietionally engage the walls of a supportingsocket, and means for clamping the plug in position on the casing,

3. A device of the class described including a casing having angularlydisposed passages for connection With a burner and gas tube,respectively, and provided with a flat base having a threaded socketformed therein, a tapered plug formed of yieldable ma terial bearingagainst the flat base of: the

tion With a gas tube, there being a threaded socket formed in the baseof the casing, a

tapered plug formed of yield-able material bearing against the base ofthe casing and provided With a central bore registering With saidsocket, the small end of the plug.

being countersunk, and a clamping screw extending through the bore ofthe plug and having its head seated in the countersunk portion of theplug and its threaded end engaging the socket.

In testimony whereof I affix my signature in presence of two witnesses.
